  • Publication number: 20230176412
    Abstract: Provided are a display panel and a display device, relating to the field of display technologies. The display panel includes a display substrate, a diffusion sheet, a transflective film, and a fingerprint identification circuit. Light of a target wavelength emitted by the fingerprint identification circuit may be reflected by an obstacle, and the light of the target wavelength reflected by the obstacle may be irradiated to the fingerprint identification circuit through at least one through hole in the diffusion sheet. The fingerprint identification circuit performs fingerprint identification according to the received light of the target wavelength reflected by the obstacle. Since an orthographic projection of the fingerprint identification circuit onto the display substrate is within a display area of the display substrate, the fingerprint identification circuit can be prevented from occupying a non-display area of the display substrate.
